. SPECIFICATION forming part of Letters Patent No. 367,884, dated August 9, 1887.

Application filed December 31, 1886. Serial No. 223,074. (No model.)

To all whom it may concern:

Be it known that I, OnAnLns C. ADELSPER- GER, a citizen of the United States, residing at Springfield, in the county of Clark'and State of Ohio, have invented certain new and useful Improvements in Shifting Seats for Vehicles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1t appertains to make and use the same, referenoe being had to the accompanying drawlugs, and to the letters and figures of reference marked thereon, which form a part ,of this specificationfand in which- Figure 1 is a perspective view of the body of a vehicle, having a portion of it broken larged scale.

away, showing both seats in position. Fig. 2 1s a sectional view of the same, showing the front seat folded back and the rear seat taking its place; and Figs. 3, 4, 5, 6, and 7 are detail views of some of the different parts on an en- This invention relates to that class of shifting seats for vehicles shown and described in my former patent, dated May 4, 1886, No. 340,970, and of which this is an improvement, as will be hereinafter more fully set-forth.

In the accompanying drawings, in which the same letters of reference indicate corresponding parts in all the figures, A represents the bottom rails of a vehicle-body, to which are secured the rocker-plates B B. To the ends of these plates are pivotally-secured the legs or supportsC, D, and E, and to the tops of these legs are secured the seat-plates F and G. The rear rocker-plates are provided'at their forward ends with a lug, H, and upon their inner side with aflange, I, and the rear seat-plates are provided upon their under sides with downwardly-projecting flanges J. The pivots by means of whichthe legs are secured to the plates, except the rear ones on the front-seat plate, consist of a conical base portion, K, and a" reduced head or point, L, and the bearings at the ends of the legs each consists of a cup-shaped recess having a perforation at its bottom, through which projects the head L, the head being made of malleable iron and riveted to secure the end of the leg, to the plate. This construction of the rivets and bearings gives agood strong support, and one which can be cheaply and quickly made.

The front legs, D D, of the rear seat are curved, as shown, and provided with two flat bearing-faces at right angles to each other, one of these faces resting upon the flange I upon the rockenplate in one position, and the other face resting against the under side of the seatplate when in the other position, the lateral motion of the seat being prevented in both positions by the flanges I and J. The rear legs, E E, of the front seat are secured to the seat-frame by means of a locking-joint, which is different from the rivet-joints above, described. The rear ends of the front-seat plates are each provided with a downwardly-project: ing lug, M, having a slot, N, in its lower portion, and is provided upon one side with two segmental flanges, O 0, one of which is formed with a shoulder, P, the ends of the two flanges being at a distance from each ot.her,thus forming sort of a notch between then]. I The upper ends of the legs which fit in these bearings are bifurcated, one side of the bifurcation being formed at its ends'with two arcs of circles, Q, and R,- oue of which is shorter than the other, and the two are joined together at one end with a shoulder, S. A pivot or bolt passes through the slot in the lug and through a perforation in each side of the bifurcation of the .leg, thus making a connection which permits of the shoulder at the top of the leg being made to engage with the shoulder at the end of one of the flanges at the side of thelug upon the seat-plate, or of being disengaged therefrom whenever desired.

Tomake the operation of the front seat automatic or subject to the movement of the rear seat, a rod or bar, T, is pivotally secured to each of the rear legs of the front seat near their lower ends and to the lower ends of the front legs, D D, of the rear seat, said legs D D being pivoted to the lugs H upon the rear rocker-plates at a short distance from their lower ends.

When it is desired to change from a twoseated to a single-seated vehicle, the lock-joint of the front seat is disengaged and the rear seat drawn forward. As the lower ends of the front legs, D D, of the rear seat are moved back by the forward movement of the seat, the front seat is drawn back toward the rear seat by the bars T T. As the front seat moves back it is drawn down toward the bottom of the vehicle, until, by the time the rear seat has come forward to near the position occupied by the front seat, the front seat has been nicely folded down under the rear seat out of the way, as shown in dotted lines in Fig. 2. 3esides making the front seat act automatically by this construction, an additional brace is given to keep it in its raised position, as the joint between the ends of the bar T and leg D is on a line with the pivots on the lug H and. on the front-seat leg, thus making the bar T act as a brace for the frontseat leg from the lug H on the rear rocker-platc. The lateral motion of the front seat when it is raised is prevented by a lug, U, upon each end of the .rockeuplate, just inside the pivot, against which the legs hear when pressed sidewisc.

Although I have shown and described the front seat as being automatically operated by means of the rear seat, it can be made to be operated independently by omitting the bar T, when the front legs of the rear seat can be socured to the end of the rocker-plate, the same as all the other legs, and the lugs II can be also dispensed with; them as shown.

\Vhen used as a double seated vehicle, it is but I prefer to make difficult to have free access to the rear seat without stepping over the front seat, unless some means are used to get it out of the way. In my former patent I showed how it could be folded forward, but I now accomplish this ob ject by securing the scat-frame to one of the scat-plates by means of a hinge, so that the seat can be turned up out of the way, as shown in dotted lines in Fig. 1. This hinge consists of a perforated lug, V, at each end of the plate, which is secured in a slot in the end of the scat-frame by means of a belt or pin. The plate at the other end of the seat is provided with two upwardly-proiccting lugs, \V, which engage with holes in the lower side of the frame, thus holding the seat very securely when being occupied.

Each end of the scat-plates is further provided with two lugs, X and Y, one of which projects from the ends of the plates and the others from the sides. A scat-guard, Z, is socured to each of the plates by means of a pin at each end of its end pieces, each end piece being bent L-shapcd, the bottom of the L resting upon the lug X, and the pin at the end fitting in the lug Y, which is perforated, and in which the pin turns as the guard is be ing turned up or down.

To prevent the end pieces of the guards from wearing the trimming upon the sides of the seat, the pins upon their ends can be made long enough to keep them from touching, or washers II can be 1ntel-posed between them. The L shape of the guards causes the top portion to standfar enough back to permit of the seat being raised at one end, and of its standing vertically at the other, thus making a very neat and convcnient construction.

Having thus described claim- 1. In a shifting seat for vehicles, the combination of the front rocker-plates, a leg pivotally secured to each end, the upper ends of two of which are bifurcated and formed into two arcs of circles joined by shoulders, two seat-plates, one end of each of which has a downwardly-extcnding lughaving a slotin its lower portion, and having two segmental flanges upon its inner side, one of which has a shoulder and pins for securing said lugs in said bifurcations.

2. In a shifting seat for vehicles, the combination of the rocker and seat plates having rivets consisting of a conical base-piece and a reduced head, and the legs having bearings at their ends consisting of cup-shaped recesses, and a perforation at their bases, the heads of said rivets being adapted to be passed through said perforations and be riveted.

3. In a shifting seat for vehicles,the combination of a front'scat plate having two perforated lugs upon its inner side, a scat-frame having two slots at one end, said lugs being adapted to be secured in said slots,and means, substantially as deseribcd,fo1.' supporting said scatat its other end.

t. In a shifting seat for vehicles,the combination of the front-seat frame pivofally sccured to its seat-plate at one end, and having two recesses at the other end,a scat-plate having two upwardly-projecting lugs upon its upmy invention, I

per side,and means,substantially as described,

for locking said seat in position.

5. In a shifting seat for vehicles,the combination of the front-seat plates, each of which is provided at its ends with two lugs, one of which is perforated and projects laterally,and a scat-guard,the end pieces of which are made L shaped, and provided with pins upon their inner ends.

In testimony whereof I affix my signature in presence of two witnesses.
